Abstract (en)
[origin: US7010134B2] A directional hearing aid comprises a front microphone ( 11 ) and a back microphone ( 12 ), a delay processor ( 13, 14 ) for processing, according to a control parameter, the respective microphone signals, and means ( 8 a) for adjusting the control parameter in order to minimize the output signal from the delay processor. The control parameter may be adjusted to change smoothly the function mode of a hearing aid between omnidirectional mode, a directional mode and a directional mode with a pair of null directions, symmetrical about the 180° direction. The directional controller may be implemented in a multichannel version. The invention provides a hearing aid, a method of controlling a hearing aid, a noise reduction system and a method of reducing noise in a hearing aid.
